Do you think something is hitting the fan? Does the change match the speed of the fan? Sometimes a leaf gets into the fan housing and hits the fan causing a ticking.

Or is the noise from under the hood, then it may be a belt idler.

Here's a question for you also...

Turn up the speed all the way, and change the direction of the vents. Let it change and wait a few seconds before changing it again. If the clicking goes away, then it might be in one of the vents.

Also, check this out.
